This, but add Soap and remove the holly and mistletoe. Sometimes my character (if tight on cash) will get Hemp instead of Silk rope. And my Druids don't bother with blankets or bedrolls, they just snuggle up with their AC :P

50 ft of string/twine. Never know when that comes in handy.
And a fishing hook.
chalk or coal
Belt pouch
map/scroll case - unless it's totally out of character to carry paper.
small steel mirror is often useful

Spell comp pouch only if I'm playing a caster
Same for holy symbols etc.

A Dagger
2-4 fishhooks
String
Twine
whetstone
Flint
A flask of oil (preferably in a metal flask)
Soap
A wine skin, start with it full of ale or wine, get your cleric to fill it as needed.
Appropriate Clothing
Rope - dealer's choice
10-25 gp towards the party tent.
7-14 days of food.
Bedroll

I am also a fan of the small, cheap items like twine, fishhook, chalk for creative problem solving ala Macgyver, and maybe some manacles. I like to use my free clothing allowance to get Cold Weather clothing, then buy myself a cheap outfit to wear most of the time. If it's not core, I am fond of getting the waterproof bag, maybe a drill. Also, at least 1 or 2 vials of acid flask, if you don't have arcane cantrips.

A few things I'd forgotten at character generation (or really couldn't afford, what with a lousy roll--60gp isn't much for a barbarian's budget!) were a crowbar for those times when +4 Str mod isn't enough, as well as a journal with pen and ink to chronicle things. As well as sometimes pass notes in-character.

I also found it amusing that I was one of the few folks in the party who did remember to buy rope.

And agreed on the sling--see earlier regarding barbarianing on a monk budget. And our cleric a few adventures later wondering what to do against a flying enemy when he'd forsaken the way of ranged weapons.

No Noble house would turn away a fellow noble. Sure they are going to wine and dine with you and try to use you now or later. But this gets you the best accommodations when traveling and frequently free access to all that other mundane gear for when you are too far between castles or cities.

Dagger - every body
Crowbar - almost everybody
rope - every body. animated rope is always good for shenanigans.
Compass - almost every body
I file most everything that is used for camping as something everyone will have, or the party will have as a group. Not everyone needs to have a cooking pot, but everyone needs a bedroll.

An Ioun lantern; do away with any and all lighting issues from the very beginning, and do so with style. If your GM allows, pitch in for a decent bestiary and atlas.

spiked gauntlet <-- best weapon in the game

Care to elaborate?

5 gold, cant be sundered, cant be disarmed, and it doesn't need to be part of your armor. and i almost forgot lets you threaten for AOO all the time.

Why can't it be sundered?

EDIT: Should be a medium, light, metal-hafted weapon. Therefore 10 hardness and 10 hp for the base version. Magical enhancements would increase the HP and hardness. Special materials aren't allowed for bonded objects. It does heal damage daily as a bonded object, but not if destroyed. Rather expensive when destroyed (200gp per wizard level).
